Donald Trump threatened to impose 17% tariffs on food and farm produce exports from Europe during talks in Washington this week, it has emerged.

Such tariffs would hit everything from Belgian chocolate to Kerrygold butter from Ireland and olive oil from Italy, Spain and France, all big sellers in the US.

First reported in the Financial Times, sources confirmed that the EU trade commissioner, Maroš Šefčovič, was given the warning on Thursday when he met the US treasure secretary, Scott Bessent, trade representative Jamieson Greer and commerce secretary Howard Lutnick.
